Question

From Homework 4-1, the following data represent the total annual salary in milions of dollars) for 10 randomly selected chief executive officers (CEO's) and the annual rate of return (in percern for the corresponding company's stock in 2009, along with a table of summary statistics for this data A table of summary statistics for this data is also provided below. -1686.445 -18.41723.130 -0.2277 In Homework 4-1, we also determined the equation of the least-squares regression line -36.116-1.050x Note: Furthermore, in Homework 4-1, we concluded that model condsions were not satisfied for this data, making any further inference on this model unreliable. Complete the ollowing. despite this fact al Calculate the coefficient of determination R2 rounded to 4 decimal places. Based on the given data, roughly % ofthe vanabity in tates of retum of company's stocks is explained by differences in their CEO's salaries. Report your answer as a percentage with two decimal places) b) The sum of squared residuals for this model is SSR Report your answer to 4 decimal places) c) The standard error of the regression model is 4decimal places Next, conduct a test of the hypotheses Report your answer to d The standard error of the slope is 1 Report your answer to4 decimal places The test statistic for this test is to Report your answer to 3 decimal places) e) The appropriate critical values for this test are sta/2- (Report only the positive value, as it appears in Table VIL) 0 Based on the above calculations, we reject/fail to reject) Ho Based on the given data, there is / is noti) a signficant inear relation between the rate of return ofa company's stock and its CEO's salary.

Answer 1

Part A:

The value of r = -0.2277

So,

R² = (-0.2277)2

Or,

R² = 0.0518

This means 5.18% of the variability is explained...
